  • the additional axles constitute, with two longitudinal members, a subframe which can be fixed in a removable manner under the chassis of the vehicle, the hubs of at least one of the two end axles being each provided with a gypsy driven with reduction by the corresponding driving wheel by means of a clutch and a set of chain wheels and chains, or of pulleys and belts mounted on a toggle joint, or of references angle with telescopic shaft, or directly by an independent electric, pneumatic or hydraulic motor for each sprocket.
  • the all-terrain and amphibious motor vehicle provided with at least two axles 1 and 2, one of which , 1, is motor, and produced by transformation of a conventional motor vehicle, is characterized in that it is provided with two additional axles 3 and 4 with independent wheels, in that a caterpillar 5 is stretched on the wheels 6 on each side of the vehicle, in that the hubs 7 of each set of wheels 6 are interconnected by a beam 8 articulated or having a certain flexibility, and in that the drive wheels 6 ′ of the vehicle are each provided with a tire 9, which has a relief cooperating with a corresponding relief from the inside of the tracks 5.
  • the vehicle according to the invention is also provided, under its chassis, with its front and rear parts , as well as on its sides of inflatable elements s 10 to 13 serving as floats after inflation.
  • the additional axles 3 and 4 are intended to ensure the tension of the tracks 5 and to relieve the original axles 1 and 2, and they can be raised by when not in use (Figure 6), for example on firm ground, and their wheels 6 can be removed in this position, so that the vehicle can be used in the usual configuration of motor vehicles, as shown in Figure 8.
  • the track of the vehicle according to the invention can be increased by adding to the hub 7 of each wheel 6 a spacer 14 .
  • the tracks 5 are advantageously each constituted by a high-strength reinforced plasticized or rubberized canvas provided at regular intervals with crosspieces 15 carrying the attachment of the tracks 5 to the ground, or even propulsion on water, and their internal fixing bar. on the tracks 5 can cooperate in the drive with the tires 9 of the drive wheels 6 '.
  • These tires 9 can advantageously be produced in the form of special tire covers, known on the market.
  • This drive could also be carried out by means of toothed or notched flanges integral with the wheels 6 ', not shown, having a profile similar to that of the tires 9, and cooperating with said internal bars of the crosspieces 15, which preferably have a section longitudinal trapezoidal.
  • the driving wheels 6 ′ can be coupled with the other wheels 6 by means of toothed wheels 16 and chains 17 as well as a clutch 18 provided on the driving axle 1. It it is also possible to ensure this coupling of the wheels by means of belts or gear trains, or by means of angular gear and cardan joints.
  • the drive of the other wheels can also be carried out directly by an independent motor for each wheel, or even by connecting the axles by a drive shaft.
  • the inflatable elements 10 to 13, shown more particularly in FIGS. 3 and 4, ensure the buoyancy of the vehicle on the water while allowing rolling.
  • These elements are generally inflated by means of a pump, a compressor, or even exhaust gases thanks to a suitable capture device, and their deflation is carried out, either simply by means of valves, or by use of '' a Venturi tube cooperating with the exhaust gases to create a suction effect.
  • the central element 10 is advantageously constituted by two compartments separated by a longitudinal central wall 21 allowing, by an over-inflation of one of the compartments, the lifting of the associated wheel train and / or the track, so that assembly and disassembly work, as well as troubleshooting are facilitated.
  • the vehicle will be steered, in a manner known per se, by braking the drive wheel or wheels on one side, for example by means of mechanisms controlled by known levers, or even by means of a special steering wheel.
  • Figure 6 shows another embodiment. tion of the invention in which only the wheels 6 of the additional axles 3 and 4 are provided with tracks 5 for use on soft ground or as an amphibious vehicle, these axles can be lifted together with the tracks for use on firm ground as a vehicle classic. In this embodiment, the vehicle can be steered by the front axle with possible braking action on one or the other track.
  • FIG. 7 shows an embodiment similar to that of FIG. 6, without a track, the wheels 6 of the additional axles 3 and 4 being able to be lowered and raised if necessary, and to be braked individually for possible assistance to the management.
  • the wheels 6 can also be arranged under the chassis of the vehicle, so as to raise the latter and obtain a narrow track, as well as to obtain, in in the case of amphibious use, an elevation of the passenger compartment relative to the waterline.
  • FIGS 9 and 10 show an alternative embodiment of the invention, in which the additional axles 22 and 25 constitute with two longitudinal members 23 a sub-frame, which can be fixed in a removable manner under the frame 24 (shown in thin dashed lines ).
  • the axles 25 On the ends of this subframe are mounted the axles 25, the axes of which are higher than those of the axles 22 and at least one of which is provided with sprockets 26 driven with gear reduction by the corresponding driving wheel 28 of the vehicle by the through a clutch 28 'and a set of chain wheels 29 and chains 30, the axis of return wheels coinciding with that of the axle of the driving wheel 28, so that the movement of the driving wheel does not modify the tension of the chains.
  • the drive could also be carried out by means of pulleys and belts, or angular gearboxes with telescopic shaft, or directly by an independent electric, pneumatic or hydraulic motor for each sprocket 26.
  • the wheels 27 of the axles 22 are independent suspension, and the axles 22 can be pivoted in use and non-use positions on the subframe by a lockable tilting device known per se.
  • the track 31, extending over the wheels 27 and on the sprockets 26, is stretched by said wheels 27, and it has a longitudinal trapezoidal section allowing better penetration into deep snow or on very loose ground, as well as an independent travel of each wheel, allowing the lower strand of the caterpillar to follow the terrain.
  • the upper part of the track 31 is supported by longitudinal sliding supports 32. These supports 32 have, between two axles 22, a space allowing the passage of the slack 33 of the track 31 in the raised position of this last (in thin lines in Figure 9).
  • the supports 32 are used for fixing the floats.
  • the axles 25 are detachably fixed to the subframe, with a tensioning device making it possible to adjust the tension of the transmission chain 30, and of the track 31.
  • one or two notches 37 made in the tracks 31 allow the free orientation of the steering wheels, and these notches can be adjusted in position by means of two marks 38 materialized on the inner face of each track, and which must be matched at the slack take-up, these pins can be combined with attachment means of the element 36, or the like.
  • the wheels 27 are driven by means of a clutch 39 and d 'a set of wheels with twin chains 40, one of which is controlled by a set of chains 41 driven by the clutch 39 by the motor shaft, and the other is connected by a chain 42 to a wheel chain 43 secured to the wheel 27, the chains 41 being tensioned by means of tensioners 44, and the travel of the intermediate wheels 27 remaining completely independent (Figure 9).
  • the axle 25 of the sprockets 26 forming the drive shaft is advantageously provided with disc or drum brakes 45 which can be actuated separately, from the cockpit, making it possible to direct the vehicle in all-terrain configuration, and serving as a safety brake in the event of a break in the drive kinematic chain.
  • the hubs of the additional wheels 27 and the sprockets 26 hubs can be equipped with multiple wheels or wheels with very wide tires to increase the contact surface on the ground, or to increase buoyancy and propulsion on water.
  • the invention it is possible to produce a versatile vehicle which can be used continuously whatever the ground conditions by simple raising or lowering of the additional wheels, and / or inflation or deflation of the inflatable elements, and / or addition or disassembly of different accessory parts.
